On a Sunset

Few things can rival the beauty of a sunset, particularly after a storm when the sky is filled with clouds. Too many clouds and it spoils the view because the sunlight can’t get through.

Ordinary beauty, yes. But still beauty.

I could probably go on discussing how the red-orange color of a sunset is due to Rayleigh scattering, but as a scholar, it’s important to know when to just sit back and admire the view.

One phenomena involving sunsets is the so called ‘green flash’, a flash of green light moments before the sun disappear in the horizon. Living so far from the ocean I must admit I’ve never seen it with my own eyes.

This was depicted in the Pirates of the Caribbean: At World’s End. There are many other atmospheric phenomena, some of them quite rare to be seen and registered, this source provides a list of them with photographic records.

But one of the most intringuing aspects of a sunset is how it’s beauty is fleeting. The sun goes down and the red light touches the clouds making them orange and then pink, and finaly blue. The sky in general, is always in constant change. You will never get to see the same sky again.

It is a privilege to be alive to witness a sunset.
